I find it a pain when I'm trying to place 'trodes on myself. I find
that sometimes I move around and yank them from my head and have to
start over again. I find sometimes that I look in the mirror, pull
hair back, abrade, swab, apply goop and get a bad connection. Oops!
I must have put the electrode a few millimeters away from the spot I
prepped... Who the f knows... Guess I'll start again, maybe this
time I'll get lucky and actually put the 'trode on the exact location
I prepped.
Sometimes I think, "Wow, I've got a spare 45 minutes, maybe I'll do
some training." Then I think, "Naw, it'll take me freakin 15 minutes
just to prep myself, forget it." Opportunity lost, game over. Hey,
at least I don't have to wash my hair again today. The only
conceivable benefit to baldness is not having to wash the trendy
10/20 "mousse" from my hair.
No, for the practitioner it's a no brainer, the goop method is not a
problem. For the home trainer, the flextrodes or a reasonable
facsimile is just what the doctor ordered. I can live with a little
saltwater in my hair, in a short time it's dry. Not da goop, not da
goop, gotta wash da goop out. So, add a wash, dry, set... Another
20 minutes and I look like I did when I started. I'm just not real
good at putting them on myself and keeping the whole process clean.
Not to mention I like the idea of some kind of head gear that can
make placement fairly consistent as well.
I ain't got anything against the goop, friend. But I only apply
these 'trodes to myself, and I'm looking for an easier way, thanks.
Not disrespectin' the goop, just supplying my opinion 'bout the
differences it will make in my simple little life (and maybe a few
others).
Now, cost is a whole other matter, which leads me back to my original
post. It seems that there is a way to build one on these
contraptions for a fraction of 200 clams...
It seems that I'm running a little low on Alpha... :-)
